Putting an 1157 LED bulbs for the brake light works fine, and that's about it. I picked up 2 pairs of white LED 194 bulbs for all 4 turn signal bulbs, and I had no luck. The LEDs themselves, replacing the bulbs, don't have enough resistance that the relay to make them flash is expecting. The LEDs come on but don't flash. I even tried some wiring and put regular bulbs in-line on the power wire before the LED, to simulate the resistance, and still no dice. Despite the simplicity of the turn signal system, it's still very finicky.
I did however get the LED bulbs I got for the extra fog lights I installed to work. Which is probably for the best cause those would've sucked the juice back consideralby. To compare, I use a special bulb in the small fog lights I got called MR11. Off the shelf at a hardware store, they come in 35W, 10W or 5W each. Combined the LED MR11's draw 1W.
The only other bulb I was able to replace and have work with any luck was I got a blue LED 194 bulb to light up the gauge cluster. I think these bulbs work only as direct illumination, not meant for flashing.
So to add to the visibility of my bike, especially at night, I picked up an amber and a red 'tire fly'. Those lights that screw onto the tire valves on your rims. Around my neck of the woods, they're technically legal cause I got 'proper' coloured ones.
